M.A.F sensor check
I have a N60 maf sitting around in my house, I want to test it to see if it is any good before I use it. Can I ohm check this? if so, how would I do it and what readings should I see.

The best info I can give you is just test it with your car. If you have a good working one and a bad working one, fuel consumption might suffer but also the ignition timing/idle control/rpm can act strange. I'm not aware of bad MAF's that don't make the engine act nervous the least. And you can voltage check it when it's running, too high voltage points to bad MAF. I don't think Ohm test would work.

I finally found evidence of having 2 bad MAF's and finally getting a 3'rd one, I ran it with the good MAF, idle was obviously less nervous, swapped it for a bad MAF and checked the RPM/ignition on Datascan. ECU instantly doesn't seem to know what to do (actually it's doing what it was programmed to do but the air measuring is so off, it ran like poo)
